Fulcrum Wind 40 DB Cykelhjul Racer

The Fulcrum Wind 40 DB road bike wheels for disc brakes offer you a variety of options. Aerodynamics and versatility have therefore been the spearheads in the development of the Wind 40 DB wheels. These wheels combine good aerodynamics with a low weight for fast acceleration and virtually no wind sensitivity. The Fulcrum Wind 40 DB is a direct derivative of the Fulcrum Wind 55 DB. Due to the rim height of 40 mm, the Wind 40 DB looks a bit more subtle in your bike and the wheels feel more stable in windy conditions or hilly areas.

The rim width of 27mm external and 19mm internal is based on the closest possible closure with 25mm or 28mm tires. This greatly reduces turbulence and resistance so that you can keep the bike up to speed more easily. Incidentally, it is possible to mount tires from 23 mm to 50 mm. The wheelset is built around aluminum hubs, CNC machined, which support the 24 straight pull spokes, guaranteeing maximum overall rigidity. You notice this both as you are speeding up and braking. The Fulcrum Wind 40 DB is the most versatile choice with a strong focus on aerodynamics for fast, flat, uphill and downhill driving.

Aerodynamics
When developing the Fulcrum Wind 40 rims, the effect of crosswinds and road stability was taken into account. The result is a wheel set that is easier to keep up to speed regardless of the circumstances. You notice this especially when you increase the pace. It takes less effort to keep the wheels straight despite any headwind or crosswind. If "Aerodynamics" and "Versatility" are the first words that come to mind to describe your ideal wheels, you may have to consider the Fulcrum Wind 40 DB wheelset as your first choice.

2-Way Fit
The Fulcrum WInd 40 DB wheels feature the 2-Way Fit technology from Fulcrum. This means that the rims are designed to offer a perfect connection to both clincher and tubeless tires. Moreover, thanks to the Mo-Mag technology, no rim tape is needed to make the rims tubeless. After all, the wheels do not have open spoke holes, but a completely closed rim bed. The Fulcrum Wind 40 DB wheels are therefore ready for use with and without inner tube.

2-WAY FIT
Tubeless's technology initially comes from the car industry, then it was taken over by the motorcycle industry, and finally it has reached the bicycle industry. After its debut in mountain biking, it is now further developed for the application in road cycling.

We have developed the 2-way fit system so that it is also compatible with regular wire and folding tires. The 2-way fit racing wheel sets are very versatile in various situations. Thanks to an edge in the rim, the tubeless tires fit perfectly to ensure maximum sealing. If the valve is positioned correctly, at first it doesn't matter whether the tire is seated completely straight; when the pressure in the tire is increased, the tire will automatically snap into place.

The benefits are unimaginable:
Tests have shown that there is a huge advantage in rolling resistance. Because no inner tube is used, the resistance completely disappears. Tubeless tires suffer nothing when the tire is punctured because of the latex in the tire the gap is filled effortlessly. Blow out or snake bite punctures are a thing of the past and safety is improved. Should it nevertheless be that the puncture is not filled after, for example, a cut in the tire, a normal inner tube can still be fitted so you can get home.

RIM DYNAMIC BALANCE
The concept is simple and elegant: Balancing the wheel with added weight exactly opposite of the valve.

DRSC - DIRECTIONATED RIM-SPOKE COUPLING
Exclusive rim / spoke connection. Makes it possible to get the exact same tension on the rim, spokes, nipples and hub in all circumstances.

MOMAG
A system where the spoke nipples can be replaced with a magnet. This is necessary when there are no spoke holes on the outside of the rim.

ANTI-ROTATION SYSTEM
This new system takes wheel spokes to a higher level. The Fulcrum engineers have adjusted the spokes and hub to create an even stiffer structure. The result is that the spokes:
Never lose their lateral stiffness, so they always stay fully centered. Maintain the tested position from the wind tunnel while driving, for maximum aerodynamic retention.

AFS AXLE SYSTEM
This is the system that Fulcrum developed for mounting the brake discs on the hubs. This fit is made so that centerlock discs perform optimally with regard to dosing and direct braking.
